Extracting Water From Manure www.ambitionias.com
  • Scientists at Michigan State University have developed a new system to extract water from manure, potentially mitigating the effects of drought and increasing the viability of farms in regions where water is an issue.
  • Named The McLanahan Nutrient Separation System, it produces water clean enough for cattle to drink by employing 3 technologies namely:
    • Ultrafiltration
    • Air Stripping
    • Reverse Osmosis
  • Manure contains about 90% of water. The system now extracts about 50 gallons of water from 100 gallons of manure with developers aiming to raise it to about 65 gallons.
  • It helps in both conserving the resources and protecting the environment as large amount of nutrients, carbon and pathogen in the manure can have detrimental effects on the environment if badly managed. Ammonia in particular affects air quality.
